WebYoung's Modulus: Also known as the Modulus of Elasticity, is a measure of material resistance to axial deformation. Its value is obtained by measuring the slope of the axial stress-strain curve in the elastic region. It is named after the English scientist Thomas Young. It is usually denoted by E, and has units of N/m 2 or lb/in 2.
